I have attached some suggestions for specifying message authentication and authorization of resources in the NIS documents and SC schema. This document is the result of a meeting held last Tues and Wednesday with Inder Monga, Jerry Sobieski, Josva Kleist, Chin Guok, Evangelos Chaniotakis, Eric Lomax, Andy Lake and Mary Thompson. I have also included the highlights of the discussion that has taken place in email.

As I have a background in distributed and grid AA issues, Inder asked me to suggest a possible attribute profile that could be adopted in the near future. I went a bit further and addressed the issue of message security as well. The attached document is for discussion and suggests alternatives and possibilities. I think the decision of what to do needs to be made by the group as a whole making the best guess they can as to what level of security the service providers will require and the users will be able to comply with.
